以下通过实施例对本发明的上述内容做进一步详细说明,但不应该将此理解为本发明上述主题的范围仅限于以下的实施例,凡基于本发明上述内容实现的技术均属于本发明的范围。
XRPD测定方法
仪器型号:Druker D8advance,靶:Cu Kα(40kV,40mA),样品到检测器距离:30cm,扫描范围:30-450(2θ值),扫描步径:0.05s。
实施例1
参照CN 105503728 B方法制备得到双唑草酮原药,为A晶型。
实施例2
将3000克双唑草酮A晶型原药置于10L的烧瓶中,加入丙酮或四氢呋喃6L,加热搅拌至原料完全溶解,之后在25℃内自然挥发,至丙酮完全挥发完毕,得到双唑草酮D晶型粉末。
实施例3
将3000克双唑草酮A晶型原药置于10L的烧瓶中,加入正辛醇6L,加热至55℃,之后,降温至0-5℃内静置结晶,过滤,干燥后得到的结晶物为D晶型。
物理化学稳定性实验
将实施例1得到的双唑草酮A晶型和实施例2-3得到的双唑草酮D晶型粉末,经过HPLC实测A晶型和D晶型含量均为96.0%左右,之后,将这两种晶型的原药分别置于25℃、40℃、55℃和70℃烘箱里面,放置2个月进行热储实验,之后测试晶型类型和纯度,结果见下表1:
